To all 'whom z'zf may concern Be it known that I, COLUMBUS P. CHAND- LER, a citizen of the United States of America, residing at Snyder, in the county of AScurry and State of Texas, have invented certain new and .useful Improvements in Boll-Veevil Destroyers, of which the following is a specification. i

This invent-ion relates to bollweevl destroyers and has for its object the provision of a machine adapted to dislodge the weevil and other noxious and destructive insects from the plants and to kill them.

Th-e machine herein shown and described is adapted to treat two rows of plants at a time and broadly speaking, it may be said to comprise tanks carrying an insecticide, beaters for dislodging the insects from the plants, aprons or conveyers and endless cond veyers or belts for carrying the dislodged insects to and discharging them into said tanks.

The machine further comprises means for creating and directing jets or blasts of air through the rows of plants simultaneously with the beating thereof to further aid in dislodging the insects.

Further objects and advantages of the invention will be set forth in the detailed description lwhich now follows:

In .the accompanying drawings, Figure 1 is a plan Vview of the machine constructed in accordance-with .the invention, Fig. 2 is a side elevation thereof, Fig. 3 is a longitudinal sectional view therethrough.

Like numerals designate corresponding parts in allo-f the figures of the drawings.

Referring to the drawings, the numeral 5 designates vthe frame of the machine. A.I main driving shaft 6 is mounted in bearings 7 .and sup orts the rear end of the frame. Ground w eels 8 .are mounted upon the opposite sides of this shaft and impart rotation to the `shaft 6 as .the machine is drawn over the ground. Shaft 6 carries a spur gear wheel 9 that meshes with a spur pinion 10 -on a transverse shaft 11. Shaft 1l carries rollers 12 and 13. There are two of the rollers 12, only one of these rollers being shown, however, 1n Fig. 1.

.Canvas belts 14 and 15 pass over the rollers 12 and 13 respectively and these belts are provided with cross bars 16 preferably formed of leather, though the invention is not limited in this respect as any form of cross .bai-sor .cleats may be employed. A

' plants.

straps 19 through which shaft 17y passes,

and it will be seen that passageways A and B are thus left upon each side of belt 13 and between said belt and the `adjacent belt 14 for the reception of thevrows of Each pair of bars' 18 carries at its forward end a roller 20 over which the belts pass and it is apparent that the upper flights of these belts will be caused to travel rearwardly when forward motion is imparted to the machine.

The rollers 2O are mounted in bearings 21 that are slotted for .the reception of bolts 22, by virtue of which construction the belts may be adjusted. longitudinally with relation to the bars 18, to thereby vary the tension of the belts. The forward end of each pair of bars is spanned by a yoke 23 to which an operating lever 24 is secured. These operating levers pass through guides 25 and 26, and the guides'26 are provided with cross bars 27 adapted to be engaged by teeth 28 of the operating levers,'to thereby provide means for vertically adjusting the forward ends of bars 18 in that-will be readily understood.

The insects carried rearwardly by the uppeiytlights of the belts are discharged into receptacles 29 that are removably supported at 30 from the rear cross bar of the machine frame, these receptacles being adapted to contain kerosene o1' other insecticide by which the insects are killed.

The shaft 6 carries a sprocket wheel 3l which, through the medium of a sprocket chainv drives a. sprocket wheel 33 upon a transverse shaft 34. Crown gears upon shaft 34 drive spur gears 36 upon shafts 37. These shafts 37 have bearingsv at 38 in yokes 39 and the yokes 39 have bearings at 40 upon shaft 34. The inner ends of shafts 37 also have bearing at 41 upon shaft 34. The 'outer ends of shaft'37 havel threaded engagement with the bodies 42 of the beaters. The beater lingers 43 are spirally arranged about. the bodies 42 and it is apparent that through the .connections described, rotation will .be imparted to .these bodies to cause the beater fingers to beat the rows of plantathereby vthe msots are dislodged and caused to fall upon the belts lei and l5.' This action is further aided by jets or blasts of air discharged through nozzles il mounted upon pipesd, and supplied through'hose lG leading from fan or blower' casings il?. The fans or blowers are driven through the medium of sprocket chains 48, small sprocket wheels t9 and large sprocket wheels 50, the latter being mounted upon shaft 6.

The forward end of the frame is supported upon ground wheels 5l mounted upon Afront axle 52 provided with the usual iifth wheel 53 and tongue 5d for the purpose of vattaching draft animals to the machine. A drivers seat 55 is arranged upon the top of the frame and to provide means for vertically adjusting the beaters, links 55 are pivoted to collars .56 embracing shafts 3T and the upper ends of these links are pivotally connected to crank arms 58 upon a transverse shaft 59. This shaft carries a crank arm GO that is connected by a link (3l with a lever This lever has a latch G25 movable over an arcuate rack @el in the usual and well known manner. This provides means accessible from the drivers seat for accomplishing the object set forth, viz., imparting swinging movement, to yokes 3S) around shaft 3l to thereby vertically adjust thebea'ters to aceonnnodate plants of varying heights.

A hood 65 is hingedly connected to the frame at 66 and covers the upper rear portion thereof, to prevent the insects dislodged from being' blown out from the rear end of the machine. This hood directs the insects downwardly and causes those dislodged but which do not fall upon the belts, to fall into the tanks direct..

The machine frame comprises inner metallic linings indicated at G7 to prevent the accidental passage of the insects through thev sides of the machine. To aid in directing the stalks of the plants into the passages A. and B, the bars 18 upon opposite sides of said passageways are curved al their forward ends to form horns and these horns are covered with metallic shields (58.

From the foregoing description, it will be seen that simple and efficient ine-ans are herein provided for accomplishing the oljects of the invention, but while the elements shown and described are well. adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes wit-hin its purview such changes as may be made within the scope of the appended claims.
